The Italy striker's next session is likely to be at Melwood after the two clubs agreed a fee for the 24-year-old, who could be signed in time to make his debut at former club Manchester City on Monday night.

"Mario Balotelli left the Milanello Sports Centre at 13:30 after having said goodbye to his team-mates," said a statement on the Serie A club's website. "The forward, before exiting through the gates, bid farewell to the press office staff. Around 50 fans were also grouped in front of the gates to say goodbye to him."

Balotelli's agent Mino Raiola is currently meeting with Liverpool representatives in England to agree personal terms over a deal that would see him return to the Premier League after just 18 months in his homeland.

Balotelli moved to Milan in January 2013 after three years at Manchester City.

The former Inter Milan forward joined Milan from Manchester City for just over £16m in January 2013. He had cost City £24m when he arrived from the Nerazzurri in 2010.

Last season, he scored 14 goals in 30 league games for Milan, and no player has scored more goals in Serie A over the 18 months he has been playing in the division.
